Calculation of exclusive cross sections with the Lorentz integral transform method

Calculation of Exclusive Cross Sections with the Lorentz Integral Transform Method

The longitudinal structure function of the d(e, ep) exclusive cross section is calculated with the Lorentz integral transform method. In this approach final state interaction is fully taken into account, but without using a final state wave function. Cross sections are obtained via the inversion of the transform. It is shown that the inversion results are very stable. The comparison to a conven...

Lorentz Integral Transform for Inclusive and Exclusive Cross Sections with the Lanczos Method

The Lorentz Integral Transform (LIT) method is reformulated via the Lanczos algorithm both for inclusive and exclusive reactions. The new technique is tested for the total photoabsorption cross section of 3H and 4He. Due to the rapid convergence of the algorithm one has a decrease in cpu time by two orders of magnitude, but at the same time an excellent agreement with the results of a conventio...

The Calculation of Photoionization Cross Sections

Fourier transform method of calculating total cross sections using the time-dependent close-coupling theory

The calculation of total integral cross sections for electron-impact ionization of atoms and atomic ions has, in the last 8 years, greatly benefited from the development of several nonperturbative methods, which generally show very good agreement with each other and with experiment. For the electron-impact ionization of hydrogen, the convergent close-coupling @1#, the hyperspherical close-coupl...
